Definitions
- Wells are often used to access resources below the surface of the earth. For instance, oil, natural gas, and water are often extracted via a well. Some wells are used to inject materials below the surface of the earth, e.g., to sequester carbon dioxide, to store natural gas for later use, or to inject steam or other substances near an oil well to enhance recovery. Due to the value of these subsurface resources, wells are often drilled at great expense, and great care is typically taken to extend their useful life.
- Chemical-injection management systems are often used to maintain a well and/or enhance well output.
- chemical-injection management systems may inject chemicals to extend the life of a well or increase the rate at which resources are extracted from a well.
- these materials are injected into the well in a controlled manner over a period of time by the chemical-injection management system.

- FIG. 7 is a partial cross-sectional view of an embodiment of the mechanical actuation system along line 7 - 7 of FIG. 6 .
- the present disclosure is generally directed toward an inline retrievable system.
- the inline retrievable system is capable of insertion and removal from a sub-sea resource (e.g., hydrocarbon) extraction system with a remotely operated vehicle (ROV), which facilitates and reduces costs for repairing, inspecting, or replacing fluid injection systems, flow meters, sensors, non-return valves, shut-off valves, throttling valves, or a combination thereof.
- ROV remotely operated vehicle
- the inline retrievable system attaches with a low lockdown force. Indeed, the inline retrievable system will experience limited or no blowout load because seals on the couplers of the inline retrievable system are pressure balanced.
- FIG. 1 depicts an exemplary sub-sea resource extraction system 10 .
- the sub-sea resource extraction system 10 may be used to extract oil, natural gas, and other related resources from a well 12 , located on a sub-sea floor 14 , to an extraction point 16 at a surface location 18 .
- the extraction point 16 may be an on-shore processing facility, an offshore rig, or any other extraction point.
- the sub-sea resource extraction system 10 may also be used to inject fluids, such as water, gas, chemicals, and so forth, into the well 12 . As the fluids flow into the well 12 the fluids may be metered by a flow meter, flow through a non-return valve, and/or be monitored by one or more sensors.
- These devices may couple to an inline retrievable system 20 for use in a Christmas tree 22 or at another location on the sub-sea resource extraction system 10 .
- the Christmas tree 22 fluidly couples to the extraction point 16 with flexible jumper or umbilical lines 24 that enable the sub-sea equipment to receive the working fluids.
- FIG. 2 is a partial perspective view of an embodiment of the Christmas tree 22 with the inline retrievable system 20 (e.g., modular unit with an insertable/in-line portion and an external portion).
- the tree 22 couples to the well 12 and may include a variety of valves, fittings, and controls for extracting resources out of the well 12 .
- the Christmas tree 22 includes the receptacle 40 that receives the inline retrievable system 20 .
- the receptacle 40 may enable fluid and electrical communication between the Christmas tree 22 and the inline retrievable system 20 .
- the inline retrievable system 20 facilitates attachment and removal of sensors, flow meters, and non-return valves among other devices.
- the inline retrievable system 20 may include a flow meter that injects water, gas, corrosion-inhibiting materials, foam-inhibiting materials, wax-inhibiting materials, antifreeze, and/or various chemicals to extend the life of a well or increase a resource (e.g., hydrocarbon) extraction rate out of the well.
- a resource e.g., hydrocarbon
- the inline retrievable system 20 simplifies construction of the subsea resource extraction system 10 by reducing the number of bends and turns that route fluid through the inline retrievable system 20 .
- FIG. 3 is a partial cross-sectional view of an embodiment of an inline retrievable system 20 in a mechanically uncoupled position.
- the inline retrievable system 20 includes a conduit 50 (i.e., an insertable/in-line portion) with a passage or aperture 52 .
- the conduit 50 rests within the receptacle 40 between the first and second openings 54 and 56 of a passage 57 .
- the receptacle 40 is generally perpendicular to the first and second openings 54 and 56 of the passage 57 , enabling alignment of the conduit 50 with the first and second openings 54 and 56 of the passage 57 .
- the conduit 50 enables fluid communication between the first and second openings 54 and 56 of the passage 57 .
- conduit aperture 52 and the first and second openings 54 and 56 form a fluid flow path 58 that enables fluid to flow through the inline retrievable system 20 and the passage 57 without bending or turning the fluid.
- the conduit 50 couples within the receptacle 40 with first and second axially movable couplers 60 and 62 that form fluid tight seals between the inline retrievable system 20 and the passage 57 of the Christmas tree 22 .
- the couplers 60 and 62 rest within respective counter bores 64 and 66 of the conduit 50 .
- the couplers 60 and 62 move in opposite axial directions 68 and 70 to mechanically couple and decouple the inline retrievable system 20 from the passage 57 of the Christmas tree 22 .
- the couplers 60 and 62 engage and disengage the respective counterbores 72 and 74 in the openings 54 and 56 of the passage 57 , to couple and decouple the conduit 50 .
- the couplers 60 and 62 may be cylindrical in shape with a hollow center (e.g., central passage 61 , 63 ) that enables fluid to flow from the passage 57 of the Christmas tree 22 through the conduit 50 and back into the passage 57 of the Christmas tree 22 .
- the couplers 60 and 62 may include multiple grooves 75 on respective exterior surfaces 76 and 78 that may receive annular gaskets 77 (e.g., metal seals, elastomeric seals, etc).
- the annular gaskets 77 form a fluid tight seal between the passage 57 of the Christmas tree 22 and the couplers 60 and 62 ; and between the conduit 50 and the couplers 60 and 62 .
- the couplers 60 and 62 axially move in response to an actuation system 80 that rests within a housing 82 (i.e., external portion of the inline retrievable system 20 ) coupled to the conduit 50 (i.e., insertable/inline portion of the inline retrievable system 20 ).
- the actuation system 80 may be a hydraulic actuation system.
- the actuation system 80 includes a hydraulic cylinder 84 with pistons 86 and 88 that move in axial directions 68 and 70 . As illustrated, the arms 90 and 92 couple to respective pistons 86 and 88 ; and to the respective couplers 60 and 62 .
- the couplers 60 and 62 also move in the axial directions 68 and 70 .
- the pistons 86 and 88 axially move in response to changing hydraulic pressure in the hydraulic cylinder 84 .
- the actuation system 80 may change the pressure in the hydraulic cylinder 84 with an internal hydraulic pump 94 (i.e., a primary hydraulic source) or through an external hydraulic fluid source 95 (i.e., a secondary hydraulic source), which pumps and removes hydraulic fluid through the external hydraulic fluid connections 96 and 98 .
- a controller 100 in the housing 50 may signal the pump 94 and/or source 95 to begin pumping fluid through hydraulic fluid lines 102 and 104 .
- the controller 100 may be an electronic control unit having a processor 99 and memory 101 , thereby enabling the controller 100 to store and execute instructions to operate the actuation system 80 , obtain feedback from sensors (e.g., block 124 ), a flow meter (e.g., block 124 ), and/or control a valve (e.g., block 124 ).
- sensors e.g., block 124
- a flow meter e.g., block 124
- a valve e.g., block 124
- the hydraulic fluid forces the pistons 86 and 88 to move axially toward one another.
- the arms 90 and 92 axially retract the couplers 60 and 62 into the housing 50 of the inline retrievable system 20 and out of the openings 54 and 56 of the passage 57 .
- an external hydraulic fluid source may pump hydraulic fluid through the hydraulic connection 96 to the hydraulic cylinder 84 through the hydraulic lines 102 and 104 , thereby hydraulically moving the pistons 86 and 88 and retracting the couplers 60 and 62 into the system 20 .
- the housing 82 includes a wall 105 that forms a sealed portion 103 of the housing 82 that receives the controller 100 .
- FIG. 4 is a partial cross-sectional view of an embodiment of an inline retrievable system 20 in a coupled position, with the coupler 60 in the counterbore 72 and the coupler 62 in the counterbore 74 of the passage 57 .
- the inline retrievable system 20 forms the fluid flow path 58 between the first and second openings 54 and 56 of the passage 57 , enabling fluid flow through the fluid conduit 50 and the passage 57 .
- the inline retrievable system 20 forms the fluid flow path 58 without bends (e.g., in-line with the passage 57 ).
- the inline retrievable system 20 attaches with a low lockdown force.
- the inline retrievable system 20 will experience limited or no blowout load because the seals 77 are pressure balanced across the couplers 60 , 62 . More specifically, the seals 77 on the first portion 126 of the couplers 60 , 62 have the same diameter as the seals 77 on the second portion 128 of the couplers 60 , 62 . The equal diameter of the seals 77 blocks unequal pressure distribution on the seals 77 . In other words, a pressurized fluid flowing through the inline retrievable system 20 will apply a force on the seals 77 on the first portion 126 that cancels the force of the pressurized fluid acting on the seals 77 on the second portion 128 of the couplers 60 , 62 .
- the actuation system 80 axially moves the couplers 60 and 62 between extended positions ( FIG. 4 ) and retracted positions ( FIG. 3 ) by pumping hydraulic fluid into the hydraulic cylinder 84 .
- the controller 100 signals the fluid pump 94 (e.g., primary hydraulic source) to pump fluid through the hydraulic line 106 to axially move the couplers 60 and 62 from the retracted positions ( FIG. 3 ) to the extended positions (e.g., coupled positions of FIG. 4 ).
- the hydraulic line 106 enables hydraulic fluid to enter between the pistons 86 and 88 , forcing the pistons 86 and 88 to move axially away from one another in the directions 68 and 70 .
- an external or secondary hydraulic fluid source 95 may pump hydraulic fluid through the connection 98 enabling hydraulic fluid to flow through the hydraulic line 106 , which moves the pistons 86 and 88 axially away from each other extending the couplers 60 and 62 into a coupled position ( FIG. 4 ). Accordingly, the inline retrievable system 20 may enable redundant or provide backup actuation of the couplers 60 and 62 .
- the inline retrievable system 20 is mechanically coupled and may be electrically coupled to the Christmas tree 22 or another structure.
- the Christmas tree 22 may include an electrical connector 120 that couples to a corresponding electrical connector 122 on the conduit 50 .
- the electrical connection ( 120 , 122 ) may enable an external controller 132 to communicate with and control the controller 100 (e.g., cross control with Christmas tree 22 or other controller), a flow meter (i.e., block 124 ), sensors (i.e., block 124 ), valves (i.e., block 124 ) or a combination thereof.
- the flow meter may accurately inject water, gas, steam, chemicals, corrosion-inhibiting materials, foam-inhibiting materials, wax-inhibiting materials, and/or antifreeze to extend the life of a well or increase the resource extraction rate from the well 12 .
- the inline retrievable system 20 may include one or more sensors that measure a property of a flow moving through the Christmas tree (e.g., fluid speed, density, material composition, temperature, pressure, corrosiveness, etc.).
- FIG. 4A is a partial sectional view of another embodiment of the inline retrievable system 20 of FIG. 4 along line 4 A- 4 A.
- the coupler 60 of the inline retrievable system 20 couples to a conduit 140 that extends from the Christmas tree 22 .
- the inline retrievable system 20 may couple to the Christmas tree 22 by driving couplers 60 , 62 over conduits (e.g., conduit 140 ); instead, of moving couplers 60 , 62 into counterbores 72 , 74 (seen in FIG. 4 ).
- the couplers 60 , 62 form a seal with the conduit 140 by including seals 77 along an interior surface 142 of the conduits 60 , 62 .
- the couplers 60 , 62 may enable a constant flow cross-section through the inline retrievable system 20 .
- FIG. 5 is a partial cross-sectional view of an embodiment of an inline retrievable system 20 with the couplers 60 and 62 in a retracted (i.e., uncoupled) position.
- the inline retrievable system 20 may include an actuation system 140 , such as a mechanical actuation system.
- the mechanical actuation system 140 includes a rotatable cam 142 that couples to the arms 90 and 92 that then couple to the couplers 60 and 62 with hinged connections 144 and 146 . In operation, rotation of the cam 142 moves the arms 90 and 92 , which axially move the couplers 60 and 62 between the retracted and extended positions (i.e., the coupled and uncoupled positions).
- the cam 142 couples to a shaft 148 that is rotatable by a motor 150 or by an external drive or tool (e.g., a remotely operated vehicle or ROV).
- a motor 150 e.g., a remotely operated vehicle or ROV.
- ROV remotely operated vehicle
- the shaft 148 rotates in clockwise direction 152 or in a counter-clockwise direction 154
- the shaft rotates the cam 142 , which moves the arms 90 and 92 coupled to the couplers 60 and 62 .
- the couplers 60 and 62 axially extend and axially retract, the inline retrievable system 20 couples and uncouples from the passage 57 of the Christmas tree 22 .
- FIG. 6 is a partial cross-sectional view of an embodiment of an inline retrievable system 20 in a coupled position, with the coupler 60 in the counterbore 72 and the coupler 62 in the counterbore 74 of the passage 57 .
- the conduit 50 forms the fluid flow path 58 between the first and second openings 54 and 56 of the passage 57 , which enables fluid to flow through the fluid conduit 50 and the passage 57 .
- the inline retrievable system 20 forms the fluid flow path 58 without bends (e.g., inline with passage 57 ).
- the inline retrievable system 20 attaches with a low lockdown force because the seals 77 are pressure balanced across the couplers 60 , 62 .
- the seals 77 on the first portion 126 of the couplers 60 , 62 have the same diameter as the seals 77 on the second portion 128 of the couplers 60 , 62 . Accordingly, a pressurized fluid flowing through the inline retrievable system 20 will apply a force on the seals 77 on the first portion 126 that is equal and opposite to the force applied to the seals 77 on the second portion 128 of the couplers 60 , 62 .
- the mechanical actuation system 140 axially moves the couplers 60 and 62 between the extended positions ( FIG. 6 ) and retracted positions ( FIG. 5 ) by rotating the cam 142 .
- the controller 100 signals the motor 150 to rotate the shaft 148 , which rotates the cam 142 and axially moves the couplers 60 and 62 in respective axial directions 68 and 70 .
- an external tool 95 e.g., a remotely operated vehicle (ROV)
- ROV remotely operated vehicle
- the inline retrievable system 20 may enable redundant or backup actuation of the couplers 60 and 62 .
- the inline retrievable system 20 is mechanically coupled and may be electrically coupled to the Christmas tree 22 or another structure.
- the Christmas tree 22 or other structure may include an electrical connector 120 that couples to a corresponding electrical connector 122 on the conduit 50 .
- the electrical connection ( 120 , 122 ) may enable an external controller 132 (e.g., a controller on the Christmas tree 22 or at the extraction point 16 ) to communicate with the controller 100 .
- the inline retrievable system 20 may include a sensor, a flow meter, and/or a non-return valve among other devices, as illustrated by block 124 .
- the flow meter may help to accurately inject water, gas, corrosion-inhibiting materials, foam-inhibiting materials, wax-inhibiting materials, chemicals, and/or antifreeze to extend the life of a well or increase the resource extraction rate from the well 12 .
- the inline retrievable system 20 may include a sensor that measures a property of the flow moving through the Christmas tree (e.g., fluid speed, density, corrosiveness, etc.).
- the inline retrievable system 20 may also include a non-return valve, alone or in combination with a flow meter and/or a sensor.
- the housing 82 includes a wall 105 that forms a sealed portion 103 of the housing 82 that receives and protects the controller 100 and motor 150 .

Abstract
Description
- This section is intended to introduce the reader to various aspects of art that may be related to various aspects of the present invention, which are described and/or claimed below. This discussion is believed to be helpful in providing the reader with background information to facilitate a better understanding of the various aspects of the present invention. Accordingly, it should be understood that these statements are to be read in this light, and not as admissions of prior art.
- Wells are often used to access resources below the surface of the earth. For instance, oil, natural gas, and water are often extracted via a well. Some wells are used to inject materials below the surface of the earth, e.g., to sequester carbon dioxide, to store natural gas for later use, or to inject steam or other substances near an oil well to enhance recovery. Due to the value of these subsurface resources, wells are often drilled at great expense, and great care is typically taken to extend their useful life.
- Chemical-injection management systems are often used to maintain a well and/or enhance well output. For example, chemical-injection management systems may inject chemicals to extend the life of a well or increase the rate at which resources are extracted from a well. Typically, these materials are injected into the well in a controlled manner over a period of time by the chemical-injection management system.
- Various features, aspects, and advantages of the present invention will become better understood when the following detailed description is read with reference to the accompanying figures in which like characters represent like parts throughout the figures, wherein:

These described embodiments are only exemplary of the present invention. Additionally, in an effort to provide a concise description of these exemplary embodiments, all features of an actual implementation may not be described in the specification. It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with system-related and business-related constraints, which may vary from one implementation to another. Moreover, it should be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure.
- The present disclosure is generally directed toward an inline retrievable system. The inline retrievable system is capable of insertion and removal from a sub-sea resource (e.g., hydrocarbon) extraction system with a remotely operated vehicle (ROV), which facilitates and reduces costs for repairing, inspecting, or replacing fluid injection systems, flow meters, sensors, non-return valves, shut-off valves, throttling valves, or a combination thereof. Moreover, the inline retrievable system attaches with a low lockdown force. Indeed, the inline retrievable system will experience limited or no blowout load because seals on the couplers of the inline retrievable system are pressure balanced.
- The inline retrievable system may couple to the subsea resource (e.g., hydrocarbon) extraction system with a hydraulic actuation system or a mechanical actuation system. The hydraulic and mechanical actuation systems may be redundantly activated with input from a controller within the inline retrievable system or with a remotely operated vehicle (ROV). The redundant activation increases the inline retrievable system's reliability in coupling and decoupling from the subsea resource (e.g., hydrocarbon) extraction system, and reduces costs for repairing the inline retrievable system. In operation, the inline retrievable system enables fluid property measurement and/or fluid control in resource (e.g., hydrocarbon) extraction operations. For example, the fluid injection system may enable fluid measurement and control to increase resource extraction or to increase the operating life of a well.

FIG. 1 depicts an exemplary sub-searesource extraction system 10. In particular, the sub-searesource extraction system 10 may be used to extract oil, natural gas, and other related resources from awell 12, located on asub-sea floor 14, to anextraction point 16 at asurface location 18. Theextraction point 16 may be an on-shore processing facility, an offshore rig, or any other extraction point. The sub-searesource extraction system 10 may also be used to inject fluids, such as water, gas, chemicals, and so forth, into thewell 12. As the fluids flow into thewell 12 the fluids may be metered by a flow meter, flow through a non-return valve, and/or be monitored by one or more sensors. These devices (e.g., a non-return valve, flow meter, and/or sensors) may couple to an inlineretrievable system 20 for use in a Christmastree 22 or at another location on the sub-searesource extraction system 10. As illustrated, the Christmastree 22 fluidly couples to theextraction point 16 with flexible jumper orumbilical lines 24 that enable the sub-sea equipment to receive the working fluids. -
FIG. 2 is a partial perspective view of an embodiment of the Christmastree 22 with the inline retrievable system 20 (e.g., modular unit with an insertable/in-line portion and an external portion). Thetree 22 couples to thewell 12 and may include a variety of valves, fittings, and controls for extracting resources out of the well 12. As illustrated, the Christmastree 22 includes thereceptacle 40 that receives the inlineretrievable system 20. Thereceptacle 40 may enable fluid and electrical communication between the Christmastree 22 and the inlineretrievable system 20. As will be explained in further detail below, the inlineretrievable system 20 facilitates attachment and removal of sensors, flow meters, and non-return valves among other devices. For example, the inlineretrievable system 20 may include a flow meter that injects water, gas, corrosion-inhibiting materials, foam-inhibiting materials, wax-inhibiting materials, antifreeze, and/or various chemicals to extend the life of a well or increase a resource (e.g., hydrocarbon) extraction rate out of the well. Moreover, the inlineretrievable system 20 simplifies construction of the subsearesource extraction system 10 by reducing the number of bends and turns that route fluid through the inlineretrievable system 20. -
FIG. 3 is a partial cross-sectional view of an embodiment of an inlineretrievable system 20 in a mechanically uncoupled position. As illustrated, the inlineretrievable system 20 includes a conduit 50 (i.e., an insertable/in-line portion) with a passage oraperture 52. Theconduit 50 rests within thereceptacle 40 between the first andsecond openings passage 57. As illustrated, thereceptacle 40 is generally perpendicular to the first andsecond openings passage 57, enabling alignment of theconduit 50 with the first andsecond openings passage 57. As illustrated, theconduit 50 enables fluid communication between the first andsecond openings passage 57. Indeed, together theconduit aperture 52 and the first andsecond openings fluid flow path 58 that enables fluid to flow through the inlineretrievable system 20 and thepassage 57 without bending or turning the fluid. Theconduit 50 couples within thereceptacle 40 with first and second axiallymovable couplers retrievable system 20 and thepassage 57 of the Christmastree 22. - The

Thecouplers central passage 61, 63) that enables fluid to flow from thepassage 57 of the Christmastree 22 through theconduit 50 and back into thepassage 57 of the Christmastree 22. Thecouplers multiple grooves 75 on respectiveexterior surfaces annular gaskets 77 form a fluid tight seal between thepassage 57 of the Christmastree 22 and thecouplers conduit 50 and thecouplers - The
couplers actuation system 80 that rests within a housing 82 (i.e., external portion of the inline retrievable system 20) coupled to the conduit 50 (i.e., insertable/inline portion of the inline retrievable system 20). In some embodiments, theactuation system 80 may be a hydraulic actuation system. Theactuation system 80 includes ahydraulic cylinder 84 withpistons axial directions arms respective pistons respective couplers pistons axial directions couplers axial directions pistons hydraulic cylinder 84. Theactuation system 80 may change the pressure in thehydraulic cylinder 84 with an internal hydraulic pump 94 (i.e., a primary hydraulic source) or through an external hydraulic fluid source 95 (i.e., a secondary hydraulic source), which pumps and removes hydraulic fluid through the externalhydraulic fluid connections controller 100 in thehousing 50 may signal thepump 94 and/orsource 95 to begin pumping fluid throughhydraulic fluid lines controller 100 may be an electronic control unit having aprocessor 99 andmemory 101, thereby enabling thecontroller 100 to store and execute instructions to operate theactuation system 80, obtain feedback from sensors (e.g., block 124), a flow meter (e.g., block 124), and/or control a valve (e.g., block 124). As the hydraulic fluid flows through thehydraulic lines pistons pistons arms couplers housing 50 of the inlineretrievable system 20 and out of theopenings passage 57. In some embodiments, an external hydraulic fluid source (e.g., ROV) may pump hydraulic fluid through thehydraulic connection 96 to thehydraulic cylinder 84 through thehydraulic lines pistons couplers system 20.
